SILU.

Appneaaonfuea .my 25, 192s. .seriai No. 1653393.

TO all cli/0m t may concer/a.'

Be it known that I, Anonrir I. ANDERSON, a citizen of the United States, residing at Zumbrota` in thecounty of Goodhue and State of Minnesota, have invented new and useful Improven'ients in Silos, of which the folles/ting is a specification.

My present invention has reference to silo construction, and has for its primary object to produce a frost-proof silo.

A further object is tosimplify and improve the existing art by constructing a silo whose outer wall is ofhollow tileand which has an inner wall of plastic material arranged directly against the outer wall for a distance from-v theV top and bottom thereo-f and from thence spaced inwardly. from said outer wall to provide a dead air space therebetween, and to further hang in the dead air space sheets of insulating material which will positively prevent dampness entering the silo.

A still further object is to produce a silo comprising inner and outer walls, the former being erected after the completion of the outer wall and wherein the outer wall is of reinforced hollow tile provided at certain of its longitudinal joints with inwardly extending bolts designed for engagement with bendable cleats and also for supporting sheets of insulating material between the cleats and the outer wall, said cleats having secured thereon metal lat-hs over which is spread a cement plaster, said cleats terminating a suitable distance from the top and bottom of the outer wall, but the plaster is continued over the inner face of all por Jrions of the wall.

The drawings which accompany and form part of this application illustrate a satis` factoryembodiment of the improvement reduced to practice, and wherein Figure l is a vertical sectional perspective view of a silo construction in accordance with this invention.

Figure 2 is a. horizontal sectional view in a line with one of the horizontal joints of the outer wall section showing the lath supporting strips before the same are bent to engage with the bolts or rivets.

Figure Sis a fragmentary sectional view substantially similar to Figure l, showing the strips bent and the metal lath secured thereon.

The remaining figures illustrate details.

My improved silomay be erected at only courses a certain amount of. ensilage in tween the walls thereof is arrangeda desi'r- `able distance from the topand bottom of the silo.

,Referring now to the drawings in detail, the numeral l designates the outer wall .of the silo. The outer wall isconstructed of of hollow" tile laidin cement and which have` their confronting surfaces pref-- era'bly` provided with interengaging means. In addition to this, the wall construction l is reinforced by metal rods prior to the insertion of the cement through the hollow body of the tiles. In the course of erection of the outer wall I arrange in certain of the horizontal joints of the tile bolt members 2 which project. a suitable distance beyond the inner face of the wall. By reference to the drawings it will be seen that the upper course of bolts are disposed a suitable distance from the top of the wall l and the lower series a` less distance from the bottom of the wall 1. These bolts are designed toprovide suspending means for sheets of in sulating paper 3, the said sheets having lapping ends and edges so that the same completely surround the wall 1. Y

The bolts 2 are designed to be passed through openings in bendable wooden strips 4. The strips are in straight condition before being arranged on the bolts which materially facilitates the erection of thesilo. When bent the strips will conform in contour to the inner surface of the wall 1, but the said strips are held spaced from the said wall l. If desired, the threaded ends of the bolts may be reduced to provide shoulders against which Vthe inner faces of the strips 4 contact, or any suitable spacing means may be provided between the strips and the outer wall l. The ends of the bolts which project through the strips may be flattened by force from a hammer or may be engaged by nuts. As a matter of fact in lieu of the bolts 2, rivets or other analogous elements may be employed.

Sustained against the innermost sheet of insulating material by the elements 2 there are metal laths, the said laths receiving thereon one or more coatings of plastic ce'-A ment 6. The cement is alsoplastered on the wall l above the uppermost and below the lowermost strips 4 and the joints between the plastered inner face of the wall l and the laths are beveled or rounded to present no sharp corners. The plastic inner face of the silo is smooth throughout so that no obstruction will be oered to the ensilage.

The double wall construction affords a dead air space to prevent frost entering the silo. The sheets of insulating material 3 prevent the passage of moisture between the walls, and it is believed that the foregoing description, when taken in connection with the drawings will fully set forth the construction and advantages of my improvement to those skilled in the art to which such inventions relate.

Having described claim 1. A silo construction comprising a reinforced outer wall of hollow tile, inwardly projecting elements thereon, sheets of insulating material suspended from said elethe invention, I

l ments and `disposed in spaced relation and with their vertical and horizontal edges overlapping, strips secured to said elements and between the spaced sheets, said strips being rounded to conform to the inner contour of the outer wall, metal lathing secured to the innermost sheet of insulating material by means of said projecting elements and a plastic facing on said metal lath.

2. A silo construction comprising a reinforced outer wall of hollow tile, inwardly projecting elements thereon, sheets of insulating material suspended from said elements and disposed in spaced relation and with their vertical and horizontal edges overlapping, strips secured to said elements and between the spaced sheets, said strips being rounded to conform to the inner contour of the outer wall, metal lathing secured to the inner most sheet of insulating material by means of said projecting elements, a plastic facing on said metal lathing and also on the inner face of the silo above and below said metal lath.

n testimony whereof I atliX my signature.
